In a population of damselflies, wings become progressively longer over the course of 8 generations. damselflies grown at high temperatures develop short wings; those grown at low temperatures develop long wings. at a given temperature, damselflies with short wings tend to have offspring with short wings and damselflies with long wings tend to have offspring with long wings. which of the following additional pieces of information would provide the strongest evidence that this is not a case of evolution? temperatures have gotten progressively hotter over the course of the 8 generations. both of the previous answers provide equally strong evidence that this is not a case of evolution. the total number of damselflies in the population has gotten progressively smaller over the course of the 8 generations.
